Cleanly separate IDL annotations from OVSDB schema information.

Until now, the OVSDB IDL annotations have been glommed together with the
schema information in a single file, and then we've used ovsdb-idlc to
extract the schema from that file.  This commit reverses the process:
the schema and the annotations are stored separately and then glommed
together as necessary at build time.

This new arrangement has a few advantages:

    - We can now easily have multiple different sets of IDL annotations
      for a single OVSDB schema.  For example, some users may not need
      access to columns that other users do.

    - Bugs in ovsdb-idlc cannot screw up the underlying schema (as shown
      by a recent commit).
